My first camper was close to the limit of my full sized Chevy with a V6 twenty years ago. I was really excited to get home and show that thing to the kids dreaming of all the fun we were going to have in it. That was a harrowing 60 mile drive from the dealership to my house. I could barely keep it at 45 or 50 MPH on the hills and people were blowing by me angrily every chance they got because I was impeding traffic. I sold that truck within a month and bought a used 3/4 ton Ford truck.
The towing experience was a night and day difference. I learned to never get that close to max ever again. Personally I need to have a lot more power so I can speed up or climb hills at the appropriate speed for the flow of traffic and the speed limits. I'm sure a lot of folks pull just fine like that but I can't stand it. It scares me when I'm flogging my truck for all she's got and barely getting up the hill with traffic piling up behind me. It's just not my bag.
My opinion is to get a lighter trailer or make a mental note to be on the lookout for a better towing vehicle in the near future. That's just too close to max to make it any fun to use unless you are camping close to home or some place with a whole lot of flat ground between the house and the campground.
Edit: Please note that I'm talking about pickups that are limited by engine power. When you start talking diesel trucks pulling FWs, they start bumping chassis limits but still have plenty of power. That's a totally different thing.
